Heat insulation coatings for outdoor textiles as well as preparation method thereof and application

Abstract

The invention provides a heat insulation coating for outdoor textiles, which comprises the components by weight portion as follows: silicon dioxide accounting for 6 to 7 parts, aluminium sesquioxide accounting for 2 to 3 parts, zinc oxide accounting for 10 to 12 parts, rutile type titanium dioxide accounting for 4 to 5 parts, PU (polyurethane) glue accounting for 80 to 100 parts, dispersing agents accounting for 0.5 to 2 parts, bridging agents accounting for 2 to 4 parts, levelling agents accounting for 0.2 to 3 parts, foam killers accounting for 0.5 to 1 part, toluene accounting for 0 to 45 parts, acetone accounting for 0 to 45 parts and antisticking agents accounting for 1 to 2 parts. The heat insulation coating is applied to synthetic fibers such as polyester and acrylon, can achieve an obvious temperature reduction effect, can be widely used on the outdoor textiles such as beach umbrellas, tents, and bicycling clothing, and can also achieve an obvious temperature reduction effect similarly when used on cellulose fiber fabrics such as cotton and flax.

Description

technical field [0001] The invention relates to a heat-insulating coating, in particular to a heat-insulating coating for outdoor textiles, a preparation method and application thereof. Background technique [0002] At present, commercial coatings specially used for thermal insulation and cooling of textiles have not yet come out, and there are few domestic and foreign literatures on this aspect. The development and production of thermal insulation and cooling coatings are mainly aimed at the fields of construction, industrial equipment and aviation. [0003] At present, there are obvious defects in the thermal insulation coatings for textiles reported at home and abroad, such as: [0004] 1. The heat insulation mechanism is single, that is, the cooling of the existing heat insulation and cooling coating is only based on one heat insulation mechanism. Such as CN1583908A has announced a kind of solar heat reflection heat insulation coating. According to the heat conduction ...

AI Technical Summary

Problems solved by technology

The cooling coating with a single mechanism cannot achieve the ideal cooling effect

[0005]2. The color is single, all limited to the white restricted area

At present, the products after coating with thermal insulation and cooling paint are all bone white, single color, and thick coating, which affects the appearance and application field of the product

For example, CN 101435158A discloses a heat-insulating and cooling paint for textiles. The heat-insulating paint contains 40-50 parts of textile emulsion, 25-35 parts of ceramic powder, and 10-20 parts of rutile titanium dioxide. A thick layer of bone white film is formed on the back cloth, which does not meet the current market requirements for diversity.

[0006]3. The function is single, or the function cannot meet the performance requirements of outdoor textiles

Outdoor textiles are exposed to the outdoor environment for a long time, and their requirements for weather resistance, aging resistance, acid resistance, alkali resistance, ultraviolet resistance and corrosion resistance are relatively high. At that time, the performance that the above outdoor textiles should have did not meet the standards

[0007]4. Existing thermal insulation and cooling coatings have complicated application process, high energy consumption and low production efficiency

Such as CN1583908A has announced a kind of solar heat reflective heat-insulating coating, and coating film drying time needs 1h, and the time of coating drying process is long like this, the energy consumption is many, has reduced processing efficiency simultaneously
